THE ULTIMATE RADIATION PYROMETER FOR UNLIMITED
APPLICATIONS IN INDUSTRY, LABORATORY & RESEARCH
The KT19 II implements the most advanced infrared technology
of the forthcoming generation. New performance features bring
added functionality beneficial to difficult and complex applications. The KT19 II sets unsurpassed standards in
radiation pyrometry. It is the ultimate high performer for non-contact temperature
measurements to cope with extremely
unfavorable boundary conditions.
The magnitude of available
options and freely
selectable operating
parameters allows
ideal adaptation for
the specific requirements of all feasible
applications.
The Optimum Instrument
for Each Application
More than 20 different models
with different spectral bands in
the range from 2 µm to 20 µm
and temperature ranges from
-100 °C to 3,000 °C are available.
A variety of interchangeable lenses and optical spacers, in conjunction with optional detector
sizes, allow focusing to more
than 530 variations of field-ofview configurations and minimum
target sizes of 0.7mm in diameter.
The World's First
Multifunctional Display
The integrated multifunctional
display, a unique implementation
in pyrometric instrumentation,
makes menu selections as easy
as a call from a cellular phone,
and allows the complete
configuration of all functions and
specific operating parameters.
High Performance in a Nut-Shell
The new KT19 II excels by a number of unequaled performance data.
The response time is adjustable from 5 msec, to monitor and control extremely short production cycles,
up to 10 minutes, to integrate measurements in long-term thermal processes with an extremely high
resolution.
The linearity error of less than 0.02 K over the entire temperature range allow calibration of the KT19 II on a
suitable blackbody calibration source with a minimum of fixed points and with high accuracy.
The complete elimination of thermal drift at low measuring temperatures by the unique chopped radiation
method and the high resolution of 10 mK are necessary prerequisites to deploy the KT19II as transfer
standard in infrared equipment calibrations.
Easy setup: Via the digital interface the KT19 II can be
configured from a PC. Transfer rate up to 115.200 bps.
Data evaluation on the PC: Measured temperature
profiles are directly displayed in Windows-graphics,
as shown below. A Multitude of Potential Applications
Interchangeable infrared lenses, optical spacers, and the option
of different detector sizes allow the choice of more than 530
optical configurations for an optimum focus on small or
extended targets.

Applications
The new instruments of the KT19 Series II incorporate
advanced signal processing based on of the latest digital
technology. The improved performance of the newly
integrated features and the open architecture of the digital
software guarantee the possibility of later upgrades for future
applications.
A special feature of the
KT19 Series II:
Emissivity, transmissivity,
and reflectivity of the
target can be separately
programmed with their
corresponding ambient
temperatures for
optimum control of
target temperatures.
As a result of the application oriented development, the
KT19 Series II covers a broad range of potential applications,
